随机一点更爽

.random() 0~1的随机数

1 import random
2 ret=random.random()
3 print(ret)
4 >>>0.03568971325272263

.randint( x，y) x~y 的随机数包过y

1 import random
2 ret=random.randint(1,3)
3 print(ret)
4 >>>3

.randrange( x,y) x~y的随机数不包过y

1 import random
2 ret=random.randrange(1,3)
3 print(ret)

.choice() 里面加可迭代对象例如：列表两个就是百分之五十的概率

1 import random
2 ret=random.choice([11,22,33])
3 print(ret)
4 >>>11

.sample() 随机选则两个

1 import random
2 ret=random.sample([11,22,33],2)
3 print(ret)
4 >>>[33, 22]

.uniform() 随机的范围

1 import random
2 ret=random.uniform(0,3)
3 print(ret)
4 >>>2.857569577421737

.shuffle() 打乱顺序

1 import random
2 v=[1,2,3,4,5,6,7]
3 random.shuffle(v)
4 print(v)
5 >>>[7, 5, 2, 4, 3, 6, 1]

验证码

 1 import random
 2 def v_code():
 3     ret=""
 4     for i in range(6):
 5         num=random.randint(0,9)
 6         alf=chr(random.randint(65,122))
 7         v=str(random.choice([num,alf]))
 8         ret+=v
 9     return ret
10 print(v_code())
11 >>>8z6bZ1
